Auala e filifili ai se tui tui

O le faʻamoemoega autu o tui tui o le faʻamamaina o vai ma aveese vaega, palapala, microorganisms, ma isi. E faʻaaogaina lautele i le biology, kemisi, saienisi o le siosiomaga, vailaʻau, ma vailaʻau.O lenei faamama e lauiloa lautele mo lona aafiaga filtration sili ona lelei, faigofie ma le lelei.Ae ui i lea, o le filifilia o le tui tui saʻo e le faigofie ma e manaʻomia le malamalama i uiga o vailaʻau faʻamama eseese ma isi mea faʻapitoa.O lenei tusiga o le a suʻesuʻeina le faʻaogaina o tui tui, uiga o mea eseese membrane, ma le auala e fai ai le filifiliga saʻo.

• Ole tele ole pore ole membrane faamama

1) Fa'amama membrane fa'atasi ai ma le tele o le pore o le 0.45 μm: fa'aaogaina mo fa'ata'ita'iga masani fa'amama vaega feavea'i ma mafai ona fa'afetaui mana'oga chromatographic lautele.

2) Filter membrane ma se pore tele o 0.22μm: E mafai ona aveesea vaega sili ona lelei i faataitaiga ma vaega feaveai faapea foi le aveesea microorganisms.

• Diamita o le membrane faamama

E masani lava, o le faʻaaogaina masani o le membrane membranes o le Φ13μm ma le Φ25μm.Mo faʻataʻitaʻiga voluma o 0-10ml, Φ13μm e mafai ona faʻaaogaina, ma mo faʻataʻitaʻiga voluma o 10-100ml, Φ25μm e mafai ona faʻaaogaina.

• Polyethersulfone (PES)

Vaega: Hydrophilic faamama membrane o loʻo i ai uiga o le maualuga o le tafe, maualalo le mafai ona faʻaaogaina, malosi lelei, e le faʻafefeteina polotini ma faʻamatalaga, ma e leai se faʻaleagaina i le faʻataʻitaʻiga.

Talosaga: Fuafuaina mo le biochemistry, suʻega, vailaʻau ma faʻamaʻi mama.

• Ester fa'afefiloi sela (MCE)

Fa'aaliga: Lapo'a tutusa pore, maualuga porosity, leai se fa'asalalauga fa'amalo, mea manifinifi, maualalo le tetee, vave filtration saoasaoa, adsorption itiiti, tau maualalo ma tau, ae le tetee i vaifofo organic ma vai malosi acid ma alkali.

Fa'aaogāga: Fa'amama o vaifofo vai po'o le fa'amama o sauniuniga e fa'afefete vevela.

• pa'u nailo (nylon)

Fa'aaliga: Lelei le vevela, e mafai ona tatalia le 121 ℃ faʻamaʻi vevela vevela vevela mo le 30 minute, faʻamautu lelei vailaʻau, e mafai ona tatalia faʻamaʻi faʻafefe, faʻafefe alkali, ava malosi, esters, suauʻu, hydrocarbons, halogenated hydrocarbons ma faʻamaʻi faʻamaʻi O ituaiga eseese o meaola ma mea faʻapitoa. fa'atasi.

Fa'aaogāga: Fa'amamāina o vaifofo vai ma vaega feavea'i.

• Polytetrafluoroethylene (PTFE)

Faʻaaliga: Ole fesoʻotaʻiga vailaʻau sili ona lautele, e mafai ona faʻafefeteina solvents organic pei ole DMSO, THF, DMF, methylene chloride, chloroform, ma isi.

Fa'aaogāga: Fa'amama uma vaifofo fa'alela'au ma vai malosi ma fa'avae, aemaise fo'i so'o malosi e le mafai e isi fa'amama mama ona talia.

• Polyvinylidene fluoride membrane (PVDF)

Faʻaaliga: O le membrane e maualuga le malosi faʻainisinia, lelei le vevela ma le faʻamautuina o vailaʻau, ma le maualalo o le protein adsorption rate;o loʻo i ai le malosi o le eletise eletise ma le hydrophobicity;ae e le mafai ona talia acetone, dichloromethane, chloroform, DMSO, ma isi.

Talosaga: Hydrophobic PVDF membrane e masani ona faʻaaogaina mo le faʻamamaina o le kesi ma le ausa, ma le suʻeina o le suavai maualuga.Hydrophilic PVDF membrane e masani ona faʻaaogaina mo togafitiga faʻamaʻi o ala o aganuʻu aganuʻu ma vaifofo, suʻega vai maualuga, ma isi.
